IVF needs to go through many stages, among which women need to go through more, whether it is examination or ovulation promotion, and then transplantation. , is not careless. But what needs to be reminded here is that men are also very important in IVF, especially in the early stage of sperm collection, which requires a lot of preparation. Only by making comprehensive preparations can you succeed in collecting sperm. Therefore, there are many precautions in the early stage of in vitro sperm extraction. Here is a summary for everyone, hoping to help everyone.

What should men pay attention to before taking sperm?

First of all, before taking sperm, the man should try to avoid smoking, drinking, infection, fatigue and so on. And it is best to abstain from sex for 3-5 days before taking sperm. Secondly, you can choose to take sperm from the hospital sperm room or collect it at home.

If you are not used to taking semen in the hospital, you should put it in a sterile container provided by the hospital through masturbation tube at home. Do not use general condoms (lest spermicide in condoms affect sperm quality) or other utensils to collect semen.

When collecting semen, hands and parts must be washed and dried first, and lubricants such as soap and emulsion are not allowed to be used to avoid affecting sperm function. Finally, take semen and send it to the laboratory at room temperature within 1 hour (if the man is inconvenient to go to the hospital that day, the woman or her family can take it to the hospital).

Prospective fathers should also pay attention to developing good living habits.

For example, no smoking, no drinking, no sauna, no staying up late and so on. In addition, you can't take medicine for tonic at will. If you must take medicine, it is recommended to consult a doctor in a regular hospital to see if taking these medicines will have an impact. The longer it takes to form good habits, the better it is for sperm, so it is recommended that prospective fathers form good habits at least three months in advance.

In addition, the prospective father must do a good job of personal hygiene before going to the hospital, and the hospital will generally prepare a wash for the prospective father. After getting the sperm cup and drip card, the prospective father needs to carefully check the specialist number and name on it.

You'd better empty your urine before entering the sperm room. Don't forget to wash your hands before taking sperm, which is also an important step. Because the sperm cup is sterile, it can only be opened during ejaculation. Don't let anything touch the inside of the cup. In addition, after taking semen, you must ring the bell window, check the information with the staff, drop a drop of semen in the sperm drip card, and finally sign for confirmation. Don't forget to lock the door when you leave and give the key to the staff at the reception desk.

Attention should be paid to sperm collection of IVF

A few months before IVF, the man should quit smoking and drinking, live a regular life and actively treat reproductive system inflammation. After entering the treatment week, according to the doctor's advice, it is estimated that the man needs to ovulate once 3-7 days before taking the eggs, and then abstain from sex until the day of taking the eggs. If semen stays in the body for too long or too short, it will affect sperm quality.

If sperm is extracted from testis or epididymis, the husband needs a minor operation to obtain sperm. If it is frozen semen or donor (mostly frozen semen), sperm should be stored in the laboratory before taking eggs, and male patients do not need to go to the clinic on the same day. Many male friends are worried before doing IVF. They are worried about their difficulty in collecting sperm and the embarrassment caused by the failure of collecting sperm on the spot.

IVF is a highly accurate operation. However, in a regular IVF operation institution, the success rate can be basically guaranteed by receiving preoperative examination and regular IVF test cycle operation in strict accordance with the doctor's guidance, and male friends who want to be IVF don't have to worry too much about the operation.
